To all who-m itmay concern:

Be it known that I, ABRAM N. PASMAN, a citizen of the United States, residing in Waterbury, in the county. of New Haven and State of Connecticut, have invented an Improvement in Flush-Valves, of which the following is a specification.

This invention relates to a flush valve adapted for use in conjunction withclosets.

same is maintained in a raised or open position by the action or pressure of the flowing water or other medium against. a vane or a plurality of vanes movably connected with the valve and adapted to bear against a portion of the tubular valve body to accomplish this result. 1 i

The present invention relates still more particularly to the form of the vane or vanes and the manner in which the same are movably-connected to the valve andv attached to one another so as to move in unison'and 'hence'irrespective of the numberof vanes tobecome substantially aunit, as will be hereinafter more particularly described.

In the drawing, 1

Figure 1 is a sectionalelevation illustrating a flush valve embodying the present invention.

Fig. 2 is also a sectional elevation on an enlarged scale, illustrating thevalve and the parts associated therewith and showing the valve in'an open position.

Fig. 3 is an inverted shown in Fig. 2.

Fig. 4 is a sectional elevation on a still larger scale'illustrating the valve and the parts associatedtherewith, and i Fig. 5is a front. elevation of one of the vanes which ismovably connected to the valve member. 1 V a Referring to the drawing, 10 indicates a tank or'other reservoir which is commonly employed with flush valves of thejgeneral' type to which this invention relates. The flush valve comprises a-pipe fitting cons1sting of alflange 11- extending from the tubular body member 12 that extends upwardly plan of the parts as into the tank from the bottom thereof and also a screw-threaded body member 13 extending through an aperture provided there for in the bottom of the tank. This fitting is secured in position in the bottom of the tank by a nut 14 being turned down against the undersurface of the tank on the screw threaded exterior of the body of the fitting or otherwise. Connected to the outer end of the fitting is a flush pipe 15, the connection being made by means of a nipple 16. This flush pipe, as'will be understood, extends to the closet or other place to be flushed.

,The valve member of the apparatus preferably comprises a ring 17 which is interiorly screw threaded and provided with a flange 18. Associated withthe ring 17 is a cap 19 having a flange 20 which is of appreciably larger diameter than the flange 18.

Fitting over the ring 17 and lying between the flanges 18 and 20 is a washer or valve-21. Aplug 22 having a square head 23 is adapted to'be turned down in the ring 17 and by means of a flange on the plug, thecap 19 is secured in position so that the washer or valve may be maintained between the flanges 18 and 20. In suitable positions in the flange 18 there are bosses 24: and connected to each of these bosses 24 is a blade. there are three bosses 24 and a corresponding number of blades indicated at 25, 26, 27. Also'as shown, each of these blades at its upper or outer end is provided with a tongue 28 which is passed through an aperture provided therefor in the corresponding boss and turned down within the recess formed by the boss so as to secure the blade in position. These parts assume an angle of 120 to each other and maybe suitably secured to one another, and furthermore are ofsuch a width as to fit and be movable within the tubular body member 12.

Associated with this valve and the blades connected therewith I employ a plurality of vanes.

to form a pocket between this flanged edge and the wings 29 and 30 of the vane. These vanes as illustrated are pivotally connected to the blade 27% indicated at 32. They are also pivotally connected by means of a link As illustrated As illustrated I have shown two ofthese vanes and they are similarly construct-1 33 which passes through a slot 34 in the blade 27 so as to permit the vanes to swing on their pivotal point 32. The link 33 as well as the pivot 32 may be made of small hollow tubes provided at their extremities with suitable washers so as to permit an appreciable lateral movement of these vanes relatively to the blade 27. Furthermore the ring 29 of each vane may be dented as indicated at 35 providing on its outer surface a boss or projection adapted to engage with a hole 36 provided therefor in the blade 27 when the parts are in the position shown in Figs. 2 and 4.

With this form of flush valve I preferably provide the pipe fitting with an offset indicated at 37 in which there is connected an overflow pipe 38 extending upwardly into the tank 10 a suflicient distance to determine the place at which the water in the tank will overflow into the pipe 38. On this overflow pipe 38 is fitted a collar 39 secured in place thereon by a set screw 40 or otherwise. The collar 39 carries a bracket 41 which at its extremity is provided with an eye 42. A rod 43 passes through the eye 42 and is suitably connected in the plug 22 so as will be apparent, to limit the upward movement of the valve and the parts associated therewith when the same are open.

The valve may be operated by means of a lever 44 pivoted adjacent one end as indicated at 45 in a bracket 46 suitably secured on the edge of the tank 10. At the end of that portion of the lever 44 which extends over the tank, the same is connected by a chain 47 with the upper end of the rod 43, while at the opposite end of the lever 44 the same is provided with a pull chain 48.

The parts of this apparatus are in their normally closed positions as indicated in Fig. 1 and in the operation of the valve and the parts associated therewith the same'are raised by pulling the chain 48 to swing the lever 44 and raise the valve, the extent of the movement of the valve being limitedby the eye 42 and the bracket 41 which act as a stop therefor. 'VVhen the valve is raised to the position shown in Fig. 2, the water or other medium in the tank 10 will flow by gravity through the pipe fitting and the pressure of the flowing water against the wings 30 of the vanes attached to the blade 27 will cause the ends 29 of the wings 29 to project beyond the upper ends of the tubular body member 12 so as to maintain the valve in an open position as long as the pressure is sufficient to support the valve. The vanes are connected, as hereinbefore described, not only to move in unison, but being flanged retard the flow ofthe water and hence increase the pressure to a greater extent than would otherwise occur. Further the bosses 35 fitting within the hole 36 tend to some extent to retard the action of the vanes in their return to the normal inoperative position and hence to retard and control the reseating of the valve against the upper end of the tubular body member which acts as a valve seat, thereby producing an even seating of the valve which is not sudden. Still furthermore, the vanes being so connected as to have an appreciable lateral play relatively to the blade in which they are connected as well as because of the dents 35 are prevented through impurities in the water from becoming inoperative through adhering to the blades to which they are attached. 7

In order to eliminate friction, as far as possible, and to prevent water adhesion, in additionrto the boss 35, I may provide the wing 29 with a boss 49, and the wing 30 with similar bosses .50 and 51.

I claim as my invention:
